I heard Abu Abdillah, peace be upon him, say: "Our first one is the ushering guide to our next one, and our next one is the conformer of the first one. And among us, the tradition is constant. Surely, when Allah ordains, He implements it." All Praise be to Allah, the Lord of all Universe and Allah bless our master Muhammad, the Prophet and his progeny and send peace upon them. Al-Shaikh al-Mufid Abu Abdillah Muhammad ibn Muhammad ibn al-Nu’man - may Allah perpetuate his capabilities - narrated to us on Monday, the end of Shawaal, in the year four hundred and four.
